2021 CHRYSLER PACIFICA Forward Collision Avoidance Automatic Emergency Braking Problems

When adaptive cruise control is enabled and I’m at cruising speed, new vehicles entering the lane in front of my vehicle are not being acknowledged leading to my vehicle getting too close and collision becoming likely. This leads to me having to takeover control frequently to prevent accidents. This happens often, not always, but it is becoming more and more frequent. This happens at all speeds from 30 mph to 70mph

1. This vehicle was recalled for a software update due to the rear camera failing to operate at times. The software was updated by the dealer. However, this did not completely fix the problem. While the camera fails less frequently, it still does not energize at times. I took the vehicle back to the dealer. I was then informed that there is water intrusion into the rear lift gate, which causes the electrical to short out. I was told that I would have to replace the wiring harness which energizes the camera as well as the rear vehicle lights. I have not noticed any problem with the lighting as of yet. However, I have been told that this is a problem with the Pacifica in general, as well as the Durango. I was told that replacing the harness would not guarantee that the problem would be solved as there would...

My Pacifica completely shut down. All the warning lights came on such as crash detected, ABS light, and the windshield wipers came on. The vehicle was towed to the dealership that I bought the vehicle from. They completed a hard reset of the vehicle, and I took it home. Two days later it did the same thing all the lights came on, but it allowed me to drive it to the dealership. Still waiting to see what they think the problem is this time.

Ghost braking. While driving on the road using the adaptive cruise control, the van initiated its braking system as if someone was in front of me. This happened with nothing in front of me for miles in sunny cool weather and while at night passing a car with fog. I assumed the fog case had some bearing as the car I was passing their tail lights appeared to illuminate the fog to a degree you would think was a car in front of me. Glove box needed to be replaced. Kept opening and slamming on my bride's chins. The trunk is soaking up water from an unknown source after heavy rains and car washes. We noticed the issue when we vacuumed the rear trunk space and took out the mat. We dried it at the local car wash and didn't think much of it until we went through a car...

On empty roads at low speeds, vehicle flashed emergency braking signs and stopped abruptly. Happened multiple times in January both in reverse and when driving forward normally. Safety of driver and passengers was impacted by the sensor issues and abrupt braking. If there were other cars behind the vehicle, it could cause accidents and injury. Vehicle was brought into dealership and could not identify or address the issue. Suggestion provided was to disable the sensors while driving.

This vehicle programming includes forward and rear collision warning with both audible and dashboard diagram lights showing which sensors are approaching another object. Unfortunately, in practice, the alarms alert you to something in front or behind you regardless of if you are in gear to move forwards or backwards. This means that everytime you get in gear to leave your parking spot the alarm is dinging because of whatever you pulled up to in your parking spot making drivers have to tune out the audible alarm which is irrelevant and look down at the dash to see where the alerting object is in relation to the vehicle. Reports have been filed with Chrysler but no action has been taken to improve this poor design despite years of it being in effect.

My 2021 Pacifica PHEV has 16,200 miles on it at time of incident on 10/31/2022. I had just pulled off the highway to get gas when the issue began. I received a “service electrical system” on the dash and a check engine light and I had to turn off and back on to get it to restart. The check engine light stayed on and upon continuing my drive home another warning light came on telling me that the emergency braking was no longer operating. The warning light stayed on for a few miles and then went off. I took snapshots I will include. I also noticed that the vehicle was recording erroneous data such as suddenly having an electrical charge of a large percent when I had zero electrical charge. I got the vehicle to the dealership for repair. On 11/1. No loaner or rental reimbursement was available from Chrysler...

I was on the highway traveling at 60mph, with the adaptive cruise control on. The semi in front of me began to brake, I tapped off the cruise control and began braking. The semi came to a complete stop and I pushed my brake pedal to the floor to stop my vehicle. It did not stop. My Pinnacle has emergency braking and forward collision warning. My driver's instrument panel did not give a forward collision warning indication in a timely manner and my emergency braking did not stop my vehicle. At the time of the accident vehicle had less than 10,000 miles, dry weather conditions, and vehicle was used for leisure - in town driving. A month previously, I took my Pinnacle into the dealership because I didn't feel my brakes were working properly. They felt mushy, little resistance, and were making a noise. An inspection was performed by the...
